It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
Sulfur, iodine, and magnesium are in different groups in the periodic table, but all three of these elements have just enough chemical character to be notable in several reactions. Sulfur is in Group 16 (chalcogens), iodine is in Group 17 (halogens), and magnesium is in Group 2 (alkaline...

What is the boiling point of oxygen? Oxygen: Oxygen is one of the 118 chemical elements that can be found on the Periodic Table of Elements. It is known by the symbol 'O' and its atomic number, 8. Oxygen is a member of Group 16, the Chalcogens, and is found in period 2 on the...
Telluride refers to a chemical compound containing the element tellurium and another element, usually a metal; tellurium is a chemical element itself, symbolized as Te and atomic number 52.
It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. How do you calculate mass number? Together, the number of protons and the number of neutrons determine an element's mass number: mass ...
